I'm using the xmlns and xsi:schemaLocation attributes in my beans tag for my applicationContext.xml file instead of using the dtd for defining DOCTYPE. The problem I'm running into is I can't define the bean tags with singleton="false". I need to have a couple of the classes in the applicationContext file as singletons, but I also need to have some of them not be singletons. There just doesn't seem to be singleton attribute available when I'm using namespace instead of a DTD. Can anyone help?
